To ALL WHOM IrMAY concerts: t

Be itknown that we, JAMES vf'tnnniu'sorr and SAMPLE C. Bruns, ofRichmond, inthe county of Wayne, and State o'f Indiana, have inventedcertain new and useful Improvements in Looms; and we do hereby declarethat the followingfis a full,rclear, and exact description thereof,reference being had to the accompanying drawings,l makingpart of thisspecification, and to the letters of reference marked thereon, likeletters'indicatig like parts wherever they occur. Y

To enable others skilled in the art to construct and use our invention,we will proceed to describe it.

Our invention relates to looms forweaving cloth, and intended for use infamilies, and our invention consiste in a novel constructionandai-rangement of the operating-mechanism, and cams-for op'e'ratingthe-treadles.

Figure 1vis a side' elevation of a loomwith our improvements applied,and V Figure 2 is a perspective view of theca'ms and treadles detachedfrom the loom.

In constructing looms of this character, it has been customary to ,useIa sliding cam for operating the treadles, and when sucllcams are used,the treadles are capable of being operated only ina certain zed order..It has also been customary to so arrange the driving-shaft and thecam-shaft that each should make the same number of revolutions. In thesetworespects our loom differs from those heretofore made. V Y

We construct a frame, A, ofthe usual form, and transversely across thefront end we mount the driving- 'shaft a, on one end of which is secureda sprocket-wheel, B. Outsideof this wheel is secured a compound crank,consisting of two parts, b and h, united by a wrist, t', as shown infig. 3. The part b forms a sh-ort'crank, to theorist t' of whichispivoted a connecting-rod or pitman, E, having its opposite end pivotedto the hatten F.

The other portion, h, is rigidly attached to the outer end of the wristz', and thus,'in effect, forms an extension of the partb, ,the Vtwoparts, b and t, thus forming a crank by which the loom is operated,there being a handle, t, attached to theend of the crank for thatpurpose. l

On the opposite end of the drivinfr-shaft a is secured a balance-wheel,D, which is connected to the hatten F on that side by a similar pitman,E, by which means the hatten is moved to and fro at each revolution ofthe Another transverse shaft', o, is mounted in the frame, in rear ofthe harness, and on this shaft is secured a series of cams, n, the form4of which is such that they can beturned-forward or backward with equalfacility, lthcir form being clearly shown in figs. 1 and '2. Upon eachof the, treadles, at the point Awhere the cam strikes it, are securedcurved piece of metal u,'upon which thecarn strikes, as represented infig. 2.

These cams are lto `be formedV and secured to the 'shaft separately, `sothat they can beremoved and have, their order or relative positionsaltered at will. It will thus be seeuthat they may be so arranged on theshaft as to operate the treadles 1, 2, 3, and 4 in regular order', or inany oth'er order desired, as, forinstance, in the order 1, 3, 2, 4, or1, 4, 2, 3, or 1, 4, 3, 2, and so on, and 4thus the loom may be madetoproduce a variety of cloths, such as cannot be produced on looms usingthe sliding cams, which are capable ot' working in a single xed orderonly.

Upon the end oi' the camshaft ois se'cu'red a sprocket-wheel, C, whichis driven. by-a chain, I, passing v around it and thel wheel B, on thedriving-shaft a, as represented in fig, 1. '.lhis wheel C is madeseveral times the size of the wheel B, (in this case four times,)whereby the cam-shaft makes but one-fourth of a revolution to euchrevolution ofthe driving-shaft. i v

'It is obvious that the .number of revolutions that the driving-shaftmakesto one of the cam-.shaft may bemore or less, the only conditionurequisite, being that the hatten shall be operated as often as a camstrikes a treadle. .I

By this arrangement of devices We dispense with all intermediategear-wheels, and, while making a loom that is extremely simple, we, atthe same time, produce one that is capable of producing a variety ofstyles of cloth.

y It is obvious that, if desired,` a. pulley may be substituted for thecrank, or that a pulley may be secured to the opposite end of thedriving-shaft, and the loom be operated by power, if desired.

Having thus described our invention, whenJ we claim is The combinaltonof the driving-shaft, having the sprocket-wheel B mounted thereon, andhaving the hatten connected thereto by-pitmen E, with the cam-shaft,having the sproeketfwheel C and the cams u secured A thereto, when saidparts are all constructedandoranged to operate substantially asdescribed.
